I installed Manjaro via architect with unconfigured plasma-desktop (very minimal, not the full plasma package).
$ xdg-open https://google.com kf.kio.widgets: KRun(0x55e7e95e4900) ERROR (stat): 123 "Could not connect to host google.com: Network unreachable." kf.notifications: Audio notification requested, but sound file from notifyrc file was not found, aborting audio notification
I am unable to open https links outside of my browser, in a libreoffice document, mumble client, etc. I have tried xdg-open and get a network unreachable error at the URL (I am able to open the URL in the browser via copy-paste).
If it is relevant, I have a system wide HTTPS_PROXY and HTTP_PROXY set in /etc/environment which is obeyed by other software without problems.
I have already set firefox as the default web browser in the system settings. What am I missing?
